Journal ArticleDOI
Molecular Mechanisms of TDP-43 Misfolding and Pathology in Amyotrophic Lateral Sclerosis.
TL;DR: The roles of TDP-43's mutations, its cytoplasmic mis-localization and aberrant post-translational modifications in ALS, its amyloid-like in vitro aggregation, its physiological vs. pathological oligomerization in vivo, liquid-liquid phase separation (LLPS), and potential prion-like propagation propensity of the TDP -43 inclusions are discussed.
Journal ArticleDOI
An acridine derivative, [4,5-bis{(N-carboxy methyl imidazolium)methyl}acridine] dibromide, shows anti-TDP-43 aggregation effect in ALS disease models

TL;DR: Among several acridine derivatives examined, AIM4, which contains polar carboxyl groups in the side arms, significantly reduces TDP-43-YFP aggregation in the powerful yeast model cell and also abolishes in vitro amyloid-like aggregation of car boxyl terminal domain of TDP -43, as observed by AFM imaging.
Journal ArticleDOI
Use of ade1 and ade2 mutations for development of a versatile red/white colour assay of amyloid-induced oxidative stress in saccharomyces cerevisiae.
TL;DR: It is hypothesize that amyloid‐induced oxidative stress would deplete reduced‐glutathione levels and thus thwart the development of red colour in ade1 or ade2 yeast.
Journal ArticleDOI
The amyloidogenicity of a C-terminal region of TDP-43 implicated in Amyotrophic Lateral Sclerosis can be affected by anions, acetylation and homodimerization.
TL;DR: It is found that kosmotropic anions greatly accelerate whereas chaotropic anions impede its aggregation, and acetylation of certain lysines in C-terminal fragments significantly reduces the TDP-432C's amyloid-like aggregation.
Journal ArticleDOI
Wild-type hen egg white lysozyme aggregation in vitro can form self-seeding amyloid conformational variants.
TL;DR: It is found that HEWL aggregates formed under quiescent versus agitated conditions, displayed different particle sizes, detergent stabilities & β-sheet content, and they only seeded monomeric H EWL under similar incubation conditions, thereby showing amyloid variant formation by HewL analogous to prion variants, which may have implications to the amyloids caused by different mutants of human lysozyme.
